A micromechanical coupled model of elastoviscoplastic deformation taking into account damage is suggested for a general stress-strain case. The model generalizes the dislocation theory of plasticity of Taylor and Gilman for the case of a softening material which a preceding fracture process. The micromechanical equations transferred to macromechanical equations using qualitative correlation relations between micro- and macroparameters. As the result we obtained the elastoviscoplastic equations for the porosity medium based on modification Gurson plasticity condition, which depend on the triaxiality coefficient. For the limiting value of the triaxiality coefficient, the change of the mechanism of the generating defects takes place (micropores are transformed to high temperature shear bands) and as the results yield condition of Gurson is transformed to Mises condition with temperature softening. Some practical examples of the applications of the suggested model are considered.
